Claudia: AI Agent

A private AI that talks, remembers, and now runs free right on your iPhone. Your chats stay on your device.

Claudia is a calm, private AI assistant for your phone.

She talks like a person. She remembers what you ask her to remember. She runs on the AI providers you already pay for, Anthropic, OpenAI, Google, and others, with no extra subscription on top.

No accounts. No login. No servers holding your conversations. Your chats live on your device.

What Claudia does

Talk by voice or text. Tap the mic and speak, or type. Claudia replies in a natural voice or on screen, whichever you prefer.

Remembers what matters. Tell Claudia a fact about yourself and she keeps it in on-device memory. She recalls it later, even in a new conversation. Everything lives in a local database on your phone.

Your voice, your choice. Use the built-in iOS voice at no cost, or bring your own ElevenLabs key for premium voice quality.

Try it without a key. A built-in demo mode runs a short sample conversation right on your device, so you can see how Claudia feels before you connect anything.

What makes Claudia different

Bring your own AI key. No monthly Claudia subscription. Use the API key you already have with Anthropic, OpenAI, Google Gemini, Groq, Cerebras, xAI, or OpenRouter. You pay the provider directly for what you use. No middleman markup.

Built for privacy. Your conversations do not pass through a Claudia server, because there is no Claudia server for them to pass through. The app talks directly to the AI provider you choose, and only after you give explicit consent for anything to leave your device.

Your keys stay yours. API keys are stored in the iOS Keychain. They are never sent anywhere except the provider you picked.

Nothing tracked. Our App Store privacy label is Data Not Collected. We do not run ads and we do not sell data, because we never collect it in the first place.

Built by an indie team

Claudia is built by PrentusAI, a small, independent shop. You bring your own AI key, the app stays out of your way, and that is the whole deal.
